Tamar A. Weinrib joined Pomerantz in early 2008. She was Of Counsel to the Firm from 2014 through 2018 and was elevated to Partner in 2019. Tamar was recognized as a 2019 Securities Litigation Super Lawyer, and was named a 2018 Rising Star under 40 years of age by Law360, a prestigious honor awarded to a select few “top litigators and dealmakers practicing at a level usually seen from veteran attorneys.” Tamar has been recognized by Super Lawyers® as a New York Metro Rising Star every year from 2014 through 2018.

In January 2019, Tamar and Managing Partner Jeremy Lieberman achieved a $27 million settlement for the Class, pending court approval, in Strougo v. Barclays PLC, a high-profile securities class action in which Pomerantz is Lead Counsel. Plaintiffs allege that Barclays PLC misled institutional investor clients about the extent of the banking giant’s use of so-called “dark pool” trading systems. This case turns on the duty of integrity owed by Barclays to its clients. In November 2016, Tamar and Jeremy achieved precedent-setting victories for investors, when the Second Circuit Court of Appeals held that direct evidence of price impact is not always necessary to demonstrate market efficiency to invoke the presumption of reliance, and that defendants seeking to rebut the presumption of reliance must do so by a preponderance of the evidence rather than merely meeting a burden of production. In 2018, Tamar successfully opposed Defendants’ petition to the Supreme Court for a writ of certiorari.

Tamar was the attorney responsible for the litigation of In re Delcath Systems, Inc. Securities Litigation, in which Pomerantz recently achieved a settlement of $8,500,000 for the Class. She successfully argued before the Second Circuit in In re China North East Petroleum Securities Litigation, to reverse the district court’s dismissal of the defendants on scienter grounds. In addition to her involvement in several other securities matters pending nationwide, Tamar is the Pomerantz attorney responsible for the litigation of KB Partners I, L.P. v. Pain Therapeutics, Inc., a securities fraud case for which Judge Sparks of the Western District of Texas recently granted final approval for a settlement of up to $8,500,000 for class members.

Before coming to Pomerantz, Tamar had over three years of experience as a litigation associate in the New York office of Clifford Chance US LLP, where she focused on complex commercial litigation. Tamar has successfully tried pro bono cases, including two criminal appeals and a housing dispute filed with the Human Rights Commission.

Tamar graduated from Fordham University School of Law in 2004 and, while there, won awards for successfully competing in and coaching Moot Court competitions.

Tamar is admitted to practice in New York, the United States District Courts for the Southern and Eastern Districts of New York, and the United States Courts of Appeals for the Second, Third, Fourth, and Ninth Circuits.
